f0 all whom it may concern.-

which are arranged independent series of Be it known that I, Gnonos OLouonnnv,

a citizen of the linited States, residing at Waterbury, in the county of New llaveir and State of Connecticut, have invented new and useful Improvements in llalhBearings, of which the following is a specification.

: able and both of which are formed with annular raceways 11 receiving the anti-frict-ional bearing balls 8, the cones being ar- The invention relates to a hall hearii'ig, I

and more particularly to the class of adjust able ball bearings.

The primary object of the invention is the provision of a bearing in which the ball cone may be adjusted, so as to compensate for wear, and that will be sustained in adjusted position, thus preventing derangement of the adjunct parts of the bearing.

Another object of the invention is the pro vision of a ball bearing in which the balls are retained in raceways provided in a sleeve and retaining cones, the cones being adjustable upon the sleeve and are held against movement relatively to the said sleeve by means of a locking device, so that the cones will be sustained in adjusted position on the sleeve.

A'further objector the invention is the provision of a ball l'iearing which is simple of construction, readily and easily cleaned, and that is thoroughly reliable and eliicient in operation, and inexpensive in production.

lVith these and other objects in view, the invention consists of the construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings: Figure 1 is a top plan view of a ball bearing constructed in accordance with the invention. Fig. 2 is a transverse sectional view on the line 22 of Fig. 1. Fig. 3 is a fragmentary vertical sectional view on the line 33 of Fig. 1. Fig. l. is a ranged concentrically about the sleeve or collar {2, and are held within the casing or shell in a manner as will be hereinafter more fully described. This shell or casing detail perspective view of a split plug member removed from the bearing.

Similar reference characters indicate corf responding parts throughout the several 1 aperture 19, the latter detachably receiving views of the drawings,

Referring to the drawings by numerals, 5 designates a fixed the ball bearing, comprising a sleeve or collar 6, the latter being suitably fixed to the shaft, so as to rotate therewith, and formed in the outer peripheral surface of the sleeve or collar 6 are spaced ball raceways rotary shaft, upon which is;

o't cylindrical shape and is formed at one end edge with an inturned annular flange 13, the latter engaging a circular groove or hearing seat 1 1 formed in 12 is preferablv the outer face of the cone 9 at the outer peripheral edge thereof. The opposite end edge of the casing or shell 12 is formed with internal threads 15, the same being engaged by comp]ementary external threads 16 provided on the cone 10 at the outer peripheral edge thereof, whereby the said cone may be adjusted in the shell for the tightening of the bearing balls or the loosening of the same in the raceways, as the occasion re quires.

The cone 10 is held locked in the sleeve by means of a locking device, comprising a pair of locking balls 17, the latter being disposed in an arcuate-shaped cam slot or groove 18 formed in the inner face of the shell or casing 12, so that the balls 17 will contact with the outer peripheral surface of the cone 10, the said groove or slot 18 being so constructed as to have its bottom wall or bed outwardly tapered toward opposite ends, whereby the balls 17, when moved therein, will become wedged between the bottom or bed of the groove, and the outer peripheral surface of the cone 10, so as to lock the latter against rotation, thereby obviating the possiliility of the binding of the bearing balls between the cone, or the loosening of the said cone 10 after the same has been adjusted.

Provided in the shell or casing 12 and intersecting the cam groove or slot 18 is an a split tubular spring plug 20, the same being formed at its outer end with internal threads 21 to be engaged by any suitable threaded tool, whereby the plug may be readily removed from the aperture When de sired. Spaced from the inner end of the in plug 20 in the outer face thereof, is formed an annular channel 22, inwhich are adapted to be seated the locking balls 17 on the insertion of the plug 20 into the aperture 19,

so as to protrude Within the cam slot or groove 18, the plug 20 being designed to separate the lockin balls 17, so as to cause the binding thereot between the bed of the cam slot and the outer peripheral surface of the cone 10, thus looking it, so that the same may be held fast in adjusted position.

What is claimed. is:

l. A ball bearing consisting of a sleeve having a raceway, a cone surrounding said sleeve and having a registering raceway, a casing surrounding said cone and provided with an opening, and a cam groove communicati ng wit-h said opening, a split tube movable in the opening and having its inner end formed with a circumsgribing groove, balls dis osed in the cam groove and adapted to be torced into locking position therein to bind against the cone by said noaavae' split tube and balls disposed in the raceways.

2. A ball bearing consisting of a sleeve having spaced raceways, a casing surrounding the sleeve and provided with a stop in one end, a cone adapted to engage said stop and provided with a raceway registering with one of the sleeve raceways, a secon cone having a raceway registering with the other sleeve raceway, said casing being provided with an opening and a cam groove communicating with said opening, locking balls disposed in said cam groove and adapted tobind against the second cone, and a split tube disposed in said opening and holding said balls in a locking position. y

In testimony whereof I afiix my signature in presence of two witnesses.
